Nanotechnology is the study of manipulating matter of molecular and atomic scale. Nanotechnology deals with developing devices, materials, other structures with at minimum dimension sized from 1 to 100 nanometres. Nanotechnology entails the application of surface science, molecular biology, semiconductor physics, micro fabrication, organic chemistry.


Nanomedicine is a branch of medicine that applies the tools and knowledge of nanotechnology in the prevention and treatment of diseases. Nanomedicine contains the use of Nano scale materials, such as biocompatible nanoparticles and Nano robots, diagnosis, actuation purposes or sensing in a living organism. Nanomedicine is medical application of Nanotechnology and Nanoscience. Nanotechnology has provided the chance of delivering drugs to particular cells using nanoparticles. Current issues for Nanomedicine involve understanding the problems related to toxicity and environmental impact of Nano scale materials.


Nanomaterials are characterized as materials with no less than one outside measurement in the size extent from around 1-100 nanometers. Nanoparticles are items with each of the three outside measurements at the Nano scale. Nanoparticles that are normally happening or are the accidental side effects of ignition procedures are generally physically and synthetically heterogeneous and frequently termed ultrafine particles. Built nanoparticles are deliberately delivered and planned with particular properties identified with shape, size, surface properties and science. These properties are reflected in mist concentrates, colloids, or powders. Regularly, the conduct of nanomaterials might depend more on surface region than molecule arrangement itself. Nanotubes, Nano clays and quantum dabs will be the quickest developing sorts. Nanoparticles with ~100 nanometers have been broadly used to progress the drug accumulation, therapeutic efficacy and internalization. The biological and physicochemical applications of the Nanoparticles can also be finely adjusted by tailoring their chemical properties, sizes, structures, morphologies, shapes, and surface properties. 


The interdisciplinary field of materials science, also commonly termed materials science and engineering is the design and discovery of new materials, particularly solids. The intellectual origins of materials science stem from the Enlightenment, when researchers began to use analytical thinking from chemistry, physics, and engineering to understand ancient, phenomenological observations in metallurgy and mineralogy. Materials science still incorporates elements of physics, chemistry, and engineering. As such, the field was long considered by academic institutions as a sub-field of these related fields. Materials science is a syncretic discipline hybridizing metallurgy, ceramics, solid-state physics, and chemistry. It is the first example of a new academic discipline emerging by fusion rather than fission.


Nanotechnology is the handling of matter on an atomic, molecular, and supramolecular scale.  The interesting aspect about nanotechnology is that the properties of many materials alter when the size scale of their dimensions approaches nanometers. Materials scientists and engineers work to understand those property changes and utilize them in the processing and manufacture of materials at the nanoscale level. The field of materials science covers the discovery, characterization, properties, and use of nanoscale materials. Nanomaterials research takes a materials science-based approach to nanotechnology, influencing advances in materials metrology and synthesis which have been developed in support of microfabrication research. Materials with structures at the nanoscale level have unique optical, electronic, or mechanical properties. Although much of nanotechnology's potential still remains un-utilized, investment in the field is booming. 

Nanotechnology is the engineering of functional systems at the molecular scale. While nanomaterials have been a part of our everyday life for quite some time, the past two decades have witnessed a fast growth of the nanotechnology sector. Nanotechnology is being used in several applications to improve the environment and to produce more efficient and cost-effective energy, as generating less pollution during the manufacture of materials, producing solar cells that generate electricity at a competitive cost, cleaning up organic chemicals polluting groundwater, clearing volatile organic compounds (VOCs) from air, and so forth.


The word nanoelectronics refer to the use of nanotechnology in electronic components. These components are commonly a few nanometers in size. The tinier electronic components turn into, the harder they are to manufacture. Nanoelectronics covers a varied set of materials and devices, with the general characteristic that they are so small that physical effects alter the material properties on a nanoscale – inter-atomic interactions and quantum mechanical properties play a important role in the workings of these devices. Nanodevices are critical enablers which will allow mankind to exploit the ultimate technical capabilities of magnetic, electronic, biological and mechanical systems.  Nanosensor can be define as a device that is able of conveying data and information about the behavior and uniqueness of nanoparticles at the nanoscale level to the macroscopic level. We have various types of nanosensors like chemical, mechanical, biological sensors.


Biomaterials are the non-drug molecules which are considered to interact with the biological system either as a part of medical device or repair or to replace any damaged organs or tissues. Biomaterials can be derived either synthetically or naturally. Tissue engineering has the possible to achieve this by combining materials design and engineering with cell therapy. Biomaterials can give physical supports for engineered tissues, powerful topographical and chemical cues to guide cells. Biomaterials engineering involves processing, synthesis and characterisation of novel materials, including glasses, polymers, cements, proteins, textile composites and hybrids. Introducing nanoscale cues such as Nano topography or nanoparticles as therapeutic agents provide an exciting approach to modulate cell behaviour. In order to probe the cell-material interface.


Graphene Nanotechnologies for Environment and Energy explores how graphene materials are being used to make very reliable, efficient devices and products for harvesting, energy storage, purification environmental monitoring. Graphene-based nanotechnologies are at the heart of some of the most exciting developments in the fields of energy and environmental research. Graphene has exceptional properties, which are being used to create more effective products for electronic systems, environmental sensing devices, energy storage, electrode materials, fuel cell, novel nano-sorbents, membrane and photocatalytic degradation of environmental pollutants especially in the field of water and wastewater treatment.

Carbon nanotubes (CNTs) are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms (graphene). They can be single-walled (SWCNT) with a diameter of less than 1 nanometer (nm) or multi-walled (MWCNT), consisting of several concentrically interlinked nanotubes, with diameters reaching more than 100 nm. Their length can reach several micrometers or even millimeters.


Polymer Nanocomposites consist of a polymer or copolymer having Nano particles isolated in the polymer matrix. Polymer nanotechnology group will develop enabling techniques for the patterning of functional surfaces. Nanotechnology has made significant contributions to the formulation of adhesives, sealants, coatings, potting and encapsulation compounds. Nanoparticle fillers such as bentonites, nano-sized silica particles and zeolites have lead to the growth of products with enhanced: tensile strength, thermal stability, chemical resistance, thermal conductivity, transparency.


Nanotechnology is impacting the podium of goods, many product that integrate nanomaterials area unit already in a very sort of items; several of which individuals don't even notice contain nanoparticles, products with recent functions starting from easy-to-clean to scratch-resistant. Samples of that car bumpers are made lighter, clothing is more stain repellant, sun cream is more energy resistant, synthetic bones are stronger, cell phone screens are lighter weight. Nanotechnology applications area unit presently being researched tested and in some cases already applied across the entire spectrum of food technology, from agriculture to food processing, packaging and food supplements. In our special Food engineering section we've ready an outline of this space.


Nanophotonics or Nano/Micro optics is the study of the behavior of light on the nanometre scale. It is define as a division of optical engineering which deals with the interaction of light with particles or substances.


Nanorobotics is the technology of creating robots or machines at nearly to the scale of a nanometer (10-9). nanorobotics refers to the still mainly theoretical nanotechnology engineering discipline of designing and construction of nanorobots. Nanorobots (nanobots or nanoids) are characteristically devices ranging in size from 0.1-10 micrometres and constructed of molecular or nanoscale components. no artificial non-biological nanorobots have so far been formed, they remain a hypothetical theory at this time. Another definition often used is a robot which allows precision interactions with nanoscale objects, or can manipulate with nanoscale resolution. Following this definition even a large apparatus such as an atomic force microscope can be considered a nanorobotic instrument when configured to perform nanomanipulation. Microrobots or macroscale robots which can move with nanoscale precision can also be considered nanorobots.


Biomedical Engineering is one of the very significant fields in engineering as it deals with interfacing the human body with electronic devices. Thus the performances of these biomedical devices need to meet the requirements. However the traditional devices lack in certain aspects due to the accessibility of compound structures. With the new advances in Nanotechnology, a large range of biomedical devices are in advance a boom in progress by overcoming the drawbacks of the conventional devices. The functions of Nanotechnology in Biomedical engineering has given rise to a drug delivery system that directly targets the affected cell, a nano capsule with camera that can be swallowed by patient for diagnosing ailments and many more such applications that make the diagnosing and treatment much simpler and the complex structures accessible. This paper reviews the advancement of biomedical applications due to the integration of Nanotechnology field

At the atomic level magnetism can be described through the overlap of electron wave functions, when taking their spin interactions into account. On the nano meter length scale it becomes more difficult to predict the behavior of a magnetic system. When reducing the size of the magnetic material the number of domains within the material will be reduced until only a single domain is obtained. By having only single domains it is possible to produce strong permanent magnets. However if the size is reduced beyond a certain limit the sample becomes superparamagnetic and does no longer hold any ferromagnetism. To produce high performance permanent magnetic the particle size should be chosen so that the coercivity is maximized together with the remanence.


Nanomedicine is a division of medicine that applies the tools and knowledge of nanotechnology in the treatment and prevention of diseases. Nanomedicine includes the use of nanoscale materials, such as Nano robots and biocompatible nanoparticles, for delivery, diagnosis, actuation purposes or sensing in a living organism. Nanomedicine is medical application of Nanoscience and Nanotechnology. Nanotechnology has provided the chance of delivering drugs to particular cells using nanoparticles. Current issues for nanomedicine involve understanding the problems related to toxicity and environmental impact of nanoscale materials.


Nanostructures are used in order to create specific nanodevices for the manipulation of biological systems at the molecular level, and this is what currently defines nanomedicine. So far, the integration of nanoparticles with biology has led to the development of diagnostic devices, contrast agents, advanced therapy applications, drug delivery therapy, and imaging approaches. Nanomedicine offers many advantages in everyday clinical practice, taking into consideration the non‐invasive approach of the samples used, fast reaction times, specificity, and sensitivity that nanoparticles can offer.


Cancer therapies are currently limited to surgery, radiation, and chemotherapy. All three methods risk damage to normal tissues or incomplete eradication of the cancer. Nanotechnology offers the means to target chemotherapies directly and selectively to cancerous cells and neoplasms, guide in surgical resection of tumors, and enhance the therapeutic efficacy of radiation-based and other current treatment modalities. All of this can add up to a decreased risk to the patient and an increased probability of survival.


There is a possible toxic effect of ultrafine particles of Nanoscale dimensions, both at the organ level as well as cellular lever, DNA repair and cellular regeneration. generally the focused area is ultrafine particles related to Carbon, or silica or metals such as titania, copper and silver. This is mostly due to their catalytic properties in their chemical capability to facilitate chemical transformation of epitopes. In wound healing Silver nanoparticles have been utilized as antimicrobial agents and are known to cause side effects. Recent advances in engineered surfaces like metal–organic or zeolites frame works are potentially cytotoxic, due to their ultrahigh surface area and potential for reactive oxygen species generation or modification of membranes, lipids, and amino acids.


DNA nanotechnology is the design and manufacture of artificial nucleic acid structures for technological uses. In this field, nucleic acids are used as non-biological engineering materials for nanotechnology rather than as the carriers of genetic information in living cells.

RNA nanotechnology is a branch of nanotechnology concerned with the design, study and application of synthetic structures based on RNA. RNA nanotechnology takes advantage of the physical and chemical properties of RNA rather than the genetic information it carries.


Tissue engineering is the usage of a group of cells, engineering and materials means and proper biochemical and physicochemical factors to rise or replace biological tissues. Tissue engineering includes the usage of a scaffold for the making of innovative feasible tissue for a medical purpose. While it was once categorized as a sub-field of biomaterials, having settled in scope, importance and it can be considered as a field in its own. 

Nanotextured substrates for tissue engineering


Nanosurgery is the term that refers to surgery that uses fast laser beams which are focused by an objective microscope lens to exert a controlled force to manipulate organelles and other subcellular structures.
